Title: Transversely heat-shrinkable plastics film - produced by spirally cutting tube of predominantly longitudinal heat-shrinkable film
IPC: B29C55/28
Filed: 1982-02-11
Abstract: Heat-shrinkable plastics film, which shrinks mainly across its width, is produced by spirally slitting a tube of plastics film which shrinks mainly along its length. Specifically a plastics tube is extruded, blown and drawn longitudinally and chilled quickly to produce film which would heat-shrink predominantly along its length. A roll (2) of this tubular film (3) is mounted on a stirrup (1) which rotates about its axis (X-X) perpendicular to the roll. The free end (4) of the film fits over a cylindrical mandrel (5), coaxial with the stirrup and rotating in the same direction at the same speed. The tubular film is continuously unrolled by the traction of rollers (51), against the outside of the tube. Level with the mandrel is a stationary cutting device (6), either a blade or a heated wire. The longitudinal advancement of the tube, combined with its rotation, causes a spiral cutting of the film against the cutter. The strip of film is wound onto a roll (8). Used for shrink-wrapping of gps. of items. It is simpler to produce longitudinally shrinking material.

Patent FR-2542363-A1 (FR)
Inventor: ROSELLI SERGIO
IPC: B60R13/06
Filed: 1983-03-09
Abstract: A gasket for joining separate panels in an edge-to-edge relation with a level surface between the panels. This device may be used for mounting a fixed glass panel such as a windshield in an opening provided in a sheet metal panel. The device comprises a U-shaped channel member for securing to the glass panel, and a contiguous sealing member which is attached to the channel member and mounts the glass in a vehicle bay. The gasket forms a contour, level with the outside surface of the sheet of glass and the car body, thereby minimizing undesirable aerodynamic effects. In a preferred embodiment of the invention, the laminated glass panel has an inner ply that extends beyond the periphery of the outer ply to form a stepped edge. The sides of the channel are shaped so that the outer side forms the same contour as the outside surface of the sheet of glass while the outer surface of the other side complements the surface of a flange in the vehicle bay in which it is mounted. The sealing member advantageously includes a rounded protruding member which engages and securely holds a portion of a rabbet in the bay and further has a hollow channel in its mid-portion which extends the length of the sealing member. This channel is deformed during the mounting of the glass panel and is filled with hardening material after the device is in place for further increasing the tightness of the seal between the glass panel and the rabbet.
